What does it do?

Pyrazinamide is used to treat tuberculosis.

How should you take it?

Take pyrazinamide regularly as directed with a glass of water.
Keep taking pyrazinamide until the course is finished, even if you start to feel better.

What if you forget a dose?

Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.
